can not get value from CTkEntry

[lautnerxing]

I want to get the value frome Entry, but when i call get_DataTransformation, the init will make its None, I don't want to create an Entry module during initialization, Because I want to reuse this class, what should i do?

the code is:

class MyConfigParams_Communication(customtkinter.CTkFrame):
    def __init__(self, master):
        super().__init__(master, width=500, height=300, border_color="black", border_width=2)

        # init_DataTransformation
        self.shortname_DTR = None
        self.eddu_DTR = None
        self.config_dict_DTR = {
            "SHORT-NAME": "SOME_IP_Default_Transformation",
            "EXECUTE-DESPITE-DATA-UNAVAILABILITY": "false"}

    def set_DataTransformation(self):
        # create label
        customtkinter.CTkLabel(self, text="SHORT-NAME: ").grid(row=0, column=0, padx=10, pady=(10, 0), sticky="e")
        customtkinter.CTkLabel(self, text="EXECUTE-DESPITE-DATA-UNAVAILABILITY: ").grid(row=1, column=0, padx=10, pady=(10, 0), sticky="e")

        # SHORT-NAME
        self.shortname_DTR = customtkinter.CTkEntry(self)
        self.shortname_DTR.insert(0, self.config_dict_DTR["SHORT-NAME"])
        self.shortname_DTR.grid(row=0, column=1, padx=10, pady=(10, 0), sticky="e")

        # EXECUTE-DESPITE-DATA-UNAVAILABILITY
        self.eddu_DTR = customtkinter.CTkEntry(self)
        self.eddu_DTR.insert(0, self.config_dict_DTR["EXECUTE-DESPITE-DATA-UNAVAILABILITY"])
        self.eddu_DTR.grid(row=1, column=1, padx=10, pady=(10, 0), sticky="e")

    def get_DataTransformation(self):
        self.config_dict_DTR["SHORT-NAME"] = self.shortname_DTR.get()
        self.config_dict_DTR["EXECUTE-DESPITE-DATA-UNAVAILABILITY"] = self.eddu_DTR.get()

        return self.config_dict_DTR

You are calling get_DataTransformation before set_DataTransformation and as the entries are created in set_DataTransformation they don't exist. I would recommend to create all widgets in the init method like this:

class MyConfigParams_Communication(customtkinter.CTkFrame):
    def __init__(self, master):
        super().__init__(master, width=500, height=300, border_color="black", border_width=2)

        # init_DataTransformation
        self.config_dict_DTR = {
            "SHORT-NAME": "SOME_IP_Default_Transformation",
            "EXECUTE-DESPITE-DATA-UNAVAILABILITY": "false"}

        # create labels
        self.label_1 = customtkinter.CTkLabel(self, text="SHORT-NAME: ")
        self.label_1.grid(row=0, column=0, padx=10, pady=(10, 0), sticky="e")
        self.label_2 =customtkinter.CTkLabel(self, text="EXECUTE-DESPITE-DATA-UNAVAILABILITY: ")
        self.label_2.grid(row=1, column=0, padx=10, pady=(10, 0), sticky="e")

        # create entries
        self.shortname_DTR = customtkinter.CTkEntry(self)
        self.shortname_DTR.grid(row=0, column=1, padx=10, pady=(10, 0), sticky="e")
        self.eddu_DTR = customtkinter.CTkEntry(self)
        self.eddu_DTR.grid(row=1, column=1, padx=10, pady=(10, 0), sticky="e")

    def set_DataTransformation(self):
        # SHORT-NAME
        self.shortname_DTR.insert(0, self.config_dict_DTR["SHORT-NAME"])

        # EXECUTE-DESPITE-DATA-UNAVAILABILITY
        self.eddu_DTR.insert(0, self.config_dict_DTR["EXECUTE-DESPITE-DATA-UNAVAILABILITY"])

    def get_DataTransformation(self):
        self.config_dict_DTR["SHORT-NAME"] = self.shortname_DTR.get()
        self.config_dict_DTR["EXECUTE-DESPITE-DATA-UNAVAILABILITY"] = self.eddu_DTR.get()

        return self.config_dict_DTR

thank you, I have already solved this problem.
But now there is another issue, When I finish filling in the data in Data Transformation and switch to the PDUs frame, if I switch back at this time, the data I previously filled in will be initialized again.
